Headphones

Grey Ghost headphones should work fine with a Tesoro right? I received my brand new set yesterday, plugged them in and maybe it's just me but they didn't seem to sound as good as a cheap set that I have used up until this point. That just doesn't seem right to me. Is there something I'm missing here?
Thanks for any advice.

What type did you Get ?

The Grey Ghost Ultimates Sucked for me on my Explorer,
Because I am hard of Hearing & they have a noise Limiter,
& so does the Explorer. Triple Whammy
Limiters on my Ears, detecor & Phones

No idea if Tesoro does also

Gray Ghost Originals. Maybe I will feel different when I get out in the field with them.

I don't have any of the latest production Grey Ghost's or other DetectorPro headphones and maybe as someone said in another forum that they have cut down the volume because of liability issues. (dudes sueing for hearing loss.) Mine are too loud so I have to have them turned down on the phones or on detector. There is a difference in the tones we can hear so maybe the cheap ones you discribe have tones you hear better, not volume.

Sandman I think your right, it's not so much the volume but the tones don't sound quite as full. On my cheap phones I hear a fuller bass I guess you could say. These almost sound like a tin can on a string. 100 plus bucks is a lot to pay expecting to get better audio. They may find themselves on an auction site. I will give them the benefit of the doubt and try them in the field, will likely be upcoming Tuesday.

Update- Once I got out in the field I found I did like these afterall. They block out all back ground noise. They are pretty comfortable after long use and I am finding/ hearing plenty.

If you want really good headphones, get a set of Bose noise cancelling headphones. The only problem is that they cost about $300.oo.

Most of us learn the hard way that a pair of $29.00 Radio Shack headphones is just as servicable in the field as a pair of $300.00 Bose headphones. It is about COMFORT, not sound quality. You ain't listening to Steely Dan..

 

[SMILEIE]

Yes, you are correct. But, after metal detecting for 5 or 6 hours I like to go home and listen to Steely Dan at high fidelity. One set of headphones can do it all.

Sound reproduction and headphones is all about Impedance.
Impedance is a combination of Ohmic Resistance and Inductive reactance to alternating current.

Mosy metal detectors are designed to operate into a headphone impedance of between 8 and 32 ohms,
(Usually marked on the HPs) which is why those cheapies from the garage sales and trash and treasure markets work so well, they are usually old stereo types that are almost always 8 ohms imp.

If you plug in a set of high impedance HPs (64 ohms and up)into a detector 8 ohm audio output the responce will be flat, possibly distorted and volume will be down.

If you connect low impedance HPs into a high impedance audio output you could possibly damage the audio output amplifyer stages.

The frequency response is also important.
metal detectors have a narrow low frequency response curve (they only generate sound in a range of between say 40hz to around 2000hz, therefore fancy wide frequency response High fidelity HPs are not required. If you connect a set of wide frequency response HPs to a detector the sound may be somewhat sharp and screechy because they are reproducing a lot of the high frequency harmonics that the cheapies will not respond to.

Most Underwater detectors use Piezioelectric HPs and are therfore High Impedance and so low impedance HPs will be no good.........Although for some reason my Infinium works great with 8 ohm headphones
